.IMPROVEMENT IN SEED-SOWING MACHlNES.

Specification forming part of Letters Patent No. 78,538, dated June $2, 1868.

TolaZZ whom it may concern,.-

Be it known that we, Jemv B. PERKINS and AI COLBURN, of Hollis, in the county of Hills borough and State of New Hampshire, have inV vented certain new and luseful .Improvements in Seed-Sewing Machines; and we do hereby declare the following to be a full and exact description thereof, reference being had to the accompanying drawings, and to the let-ters of reference marked thereon.

To enable others skilled in the art to make and use our invention, we will proceed to describe its nature, construction, and use.

The nature o't' our invention consists in a peculiar combination and arrangement of parts, which can only be understood by inspect-ion ofthe drawings and spccitieation.

ln the drawings, Figure l is an elevation with one of the wheels removed. Fig. 2 is a horizontal section on the line .1; y, Fig. l, showing all parts below the section-line in plan.

The construction of our improved sewer is fol l ews A is a handle to which side pieces, A Ai', are attached. .lhrough these side pieces the aXle F passes, towhich mile the seed-drum F and the wheels D D are attached.

B is a hopper, the opening in the bot-tom of which is occupied by the seed-drum F. This seed-drum F has a small channel, O O, Fig. 2, passing around it,and a number of small recesses, one of which, N, is shown in Fig. 2.

As 'theserecesses pass the opening at the bot-- 'toni of the hopper they receive the seeds, and

carrying them around drop them into the opening I?, Fig. 2, indicated by dotted lines in Fig. l'.

K is a vibrating arm, which extends to the openingjinthe bottom ot" the hopper, and serves to stir the seeds, and thus keep them from packing. This arm is vibrated b v the I pins H H, Fig. l, which, being attached to the axle, come in Contact with thelever K, to which the vibrating arm K' is attached. The spring I, Fig. l, snaps the lever K back to place when released by the pins H.

. AC is a -bealn vibrating upon a pin, S', Fig.

l. To the lowerend of this beam the plow U is attached, which serves to make a` furrow into which the Seeds passing through the perforations P drop.

Attached to the upper end of the beam C is a spring, E, which allows the plow to yield to and pass over any obstruct-ions which it may meet. The beam C may be raised or lowered by changing the pin S to S or S. l

V is a eoverer pivoted to the beam C by the pin or pivot T. If desirable, a number of these devices for making the furrow, dropping the seed, and covering may be attached to a single shaft and pair ot' wheels, so that a number of rows of seeds may be planted at the same time.I

Vhat we claim as our invention is l. The vibrating plow-.beam C, held by the spring E, in eonibination with the cover-er V,

varranged substantially as described, and for the purpose set forth.

2. The agitator l', arranged and. operated substantially as described and for thcpurpose set forth. 1 y
